In any world with either parent or child sub-account, Minecraft flashes a red screen and closes within 6 seconds of the world loading. The program will sit open on the menu/settings pages all day, but as soon as a world is loaded, it crashes. All media drivers are up to date. No mods active. Tried troubleshooting from other crashing tip pages with no luck. Minecraft just purchased and downloaded on Aug 4, 2020.
